OVERVIEW:
What is the protein CSF lab test?
The protein CSF is a lab test that determines the amount of protein present in cerebrospinal fluid. Cerebrospinal fluid is a clear fluid that surrounds and cushions the brain and spinal cord.
Why is the protein CSF test done?
The protein CSF lab test is done to diagnose the following conditions:
- Tumours,
- Infection,
- Inflammation of several groups of nerve cells,
- Vasculitis,
- Blood in the spinal fluid,
- Multiple sclerosis.
What does protein CSF test measure?
The protein CSF test measures the amount of protein present in cerebrospinal fluid.
What do high protein levels in CSF indicate?
An abnormal protein level in the CSF indicates a problem in the central nervous system.
What does low CSF protein mean?
Low CSF protein level can occur in conditions such as a repeated lumbar puncture or chronic leak.
What are the risks associated with this test?
Common risks associated with this test are:
- Bleeding into the spine,
- Allergic reaction to anaesthetic,
- Infection,
- Damage to the spinal cord if you move.
Is the CSF test painful?
A protein CSF lab test is done under the influence of anaesthesia, hence, you will not feel any pain during the procedure.
What is the normal CSF cell count?
Normally there are no red blood cells in the CSF and no more than 5 white blood cells per cubic millimetre of CSF.
The normal level of protein in CSF varies between 15mg/dL to 60mg/dL or 0.15mg/mL to 0.6mg/mL. Any protein CSF value higher than normal suggests a problem in the central nervous system.
The protein CSF lab test is done for the diagnosis of the following conditions:
- Meningitis,
- Head injury,
- Tumours,
- Infection,
- Inflammation of several groups of nerve cells,
- Vasculitis,
- Blood in the spinal fluid,
- Multiple sclerosis.
